Poly(ethylene terephalate) prepolymer graft modification of nano-TiO 2 and its effect on mechanical property of polycarbonate nanocomposites

Abstract

Nano-TiO₂ particles were modified by the poly(ethylene terephalate) prepolymer (pre-PET) via polycondensation. Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy results showed that pre-PET was successfully grafted on the surface of the nano-TiO₂ particles. Thermogravimetric analysis results indicated that the grafting efficiency depended on the vacuum degree. Compared to the original nano-TiO₂, the grafted nano-TiO₂ had better compatibility with the polycarbonate (PC) matrix and could be dispersed more homogeneously in PC. Hence, interfacial adhesion between TiO₂ and PC was enhanced. The mechanical properties of the resultant PC/nano-TiO₂ composites like tensile strength and notched impact strength were greatly improved. Calculated respectively from tensile yield stress PC/nano-TiO₂ composites, the interfacial interaction parameter B was employed to quantitatively characterise the effective interfacial interaction between the nano-TiO₂ and PC matrix. It demonstrated that the nano-TiO₂ grafted with pre-PET had stronger effective interfacial interaction with PC matrix than original nano-TiO₂.
